Quasi-ordered plasmonic metasurfaces with unclonable stochastic scattering for secure authentication.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Quasi-order in structural coloration, as observed in nature, offers intrinsic, unclonable near-field stochastic fingerprints while preserving far-field uniform colors. However, replicating this balance in artificial photonic metasurfaces remains a major challenge. Here, we present plasmonic metasurfaces that achieve this balance through electrostatic self-assembly of quasi-ordered gold nanoparticles onto a dielectric-spaced metallic mirror. These metasurfaces enable precise tuning of far-field reflective colors across the visible spectrum by adjusting the dielectric gap thickness, while simultaneously generating stochastic near-field scattering patterns that serve as unique physically unclonable functions (PUFs). The resulting scattering PUF keys exhibit uniform bit uniformity (average: 0.501), high uniqueness (inter-Hamming distance: 0.496) and large capacity (~10
